To a. whmn it TMJfl/Z/ concern:

Be it known that I, WILLIAM WALTER MOORE, a citizen of the UnitedStates, resid ing and having my post-office address at Lansing, in thecounty of Ingham and State of Michigan, have invented. certain new anduseful Improvements in Railroad-Gates, of which the following is aspecification.

This invention relates to improvements in gates to be employed at theintersection of roads or streets, and .more particularly at such pointswhere one or both of the intersecting roads or streets are utilized by arailway.)

The improvements reside in the provision of operating instrumentalitiesfor the gates arranged above the surface of the ground, whereby they areconstantly observable and readily adjusted and repaired should occasiontherefor arise, thereby overcoming the disadvantages and relativeunreliability of such structures as employ underground mechanlsms.

The invention also embraces a series of supports for swinging gatemembers, operating means therefor and means operatively associatedtherewith, whereby the gate mem bers are mutually balanced; and itfurther comprehends means for mounting the gate members, whereby undernormal conditions they will occupy the position of and serve as abarrier crosswise of the roadway, but when subjected to abnormal forcewill yield sufficiently to preserve the parts against breakage ordisarrangement.

The foregoing, as well as other novel de tails in the construction andarrangement of the several parts of the invention, will be apparent fromthe detailed description hereinafter when read in connection with theaccompanying drawings, forming part hereof, and wherein a convenientembodiment of the invention is illustrated.

In the drawings, Figure 1 is a perspective of two pairs of gates and theoperating means therefor, arranged at the intersectionof roadways, theview being taken from a position above it and looking downwardlythereupon. Fig. 2 is a somewhat enlarged perspective of the lowerportion of one of the columns or masts, parts being broken away. Fig. 3is a view 011 line ac cc of Fig. 1 and. Fig. 4 is an elevation lookingin the direction of the arrow, Fig. 1. 1

Referring more specifically to the drawings, wherein like referencecharacters refer to corresponding parts in the/several views,

E on said tower.

A represents towers or masts, which are preferably hollow castings orpiping, mount ed with their lower ends extending below the groundsurface and each embedded in a con'- crete foundation a. The towers arearranged in pairs on opposite sides of the roadway, as clearly shown inFig. 1, and have laterally= projecting relatively short arms I), whichserve as supports for the gate members C, now to be defined. Each gateis composed of two parts, the inner being shown at c, pivotedintermediate its ends, as at n, to the masts A, and having at its outerend p a cavity a for the reception of balancing material or weights,said cavity being indicated at u. The inner end of this member 0isforked, as at q, to constitute superposed ears for the re ception ofthe inner extremity of the mem-- ber K or gate proper, the two membersbeing connected through the medium of a pintleand-spring connection N,which normally acts to maintain the member K in a position ofsubstantially true alinement with the member 0, but which when abnormalforce is applied to the member K, as may arise in the case of runawayanimals and vehicles, will yield against the tension of the spring, andthereby preserve the parts against breakage or disarrangement, as isobvious.

Near the tops of the towers are pivotally mounted four-armed levers E,the horizontal arms of which are connected by links D to the gatemembers a, and by links D to gates L, adapted to extend across thesidewalk or the like. The alternate extremities of the fourarmed leversare also connected by links H, the effect of crossing these links beingto reverse the direction of motion of the four armed levers whenrevolved on a pivot. A winch R, to which motion is given by its crank ror other means, has cords F passing around it and around a pulley G,carried by a removable and adjustable band or bracket g, mounted on thetower A located nearest thereto, and thence over pulleys g, similarlymounted at a higher point on the tower, whence the ex: tremities arecarried down and connected to the horizontal extremities of thecross-arms When four gates are used, a second system of cords F passesaround the same winch, thence around other pulleys g on the same towerA, thence to the top of the tower over pulleys 9 from whence they crossthe roadway to corresponding pulleys g at the top of the opposite towerat the opposite side of the track or roadway, the terminals in thisinstance being connected to the horizontal four-armed levers E on saidlast-mentioned tower. Those operating portions of the cords between thevarious pulleys may be metal links or rods, as shown, the ends of whichare united by flexible chains running aroundsaid pulleys.

The gates L are pivoted intermediate their ends, as at Z, to the ends ofthe arms b, and in some instances may have operative connec tion withthe adjoining gates through the medium of segments 0, so as to bedependent on each other in their movements, which arrangement alsoenables me to dispense with onelz of the connecting-links D, asindicated at .All of the link connections have turnbuckles to facilitatetheir adjustment.

When the winch R is caused to revolve, it draws upon the cord on oneside of the barrel and correspondingly relaxes those on the oppositeside. The cords, passing over their respective pulleys, draw upon thecorresponding extremities of the four-armed levers E and raise thoseextremities and by means of the links d raise the gates. When thedirection of motion of the winch is reversed, the opposite cords aredrawn upon and the gates are lowered.

Although it is unnecessary to illustrate the same, I may add that thewinch may be mounted in any ordinary switch tower or station or otherhousing, or it may be mounted directly upon the base of one of thetowers, as shown.

Changes in the construction and arrangement of the several parts may bemade without departing from the spirit of the invention, and it is alsoto be understood that the invention is susceptible of still otherembodiments than those disclosed herein.

Having thus described the invention, what is claimed as new, and desiredto be secured by Letters Patent, is

1. In combination, vertical towers, gates pivotally mounted on saidtowers and near the base thereof, rotatable members pivotally mounted onsaid towers and near the top thereof, links connecting oppositeextremities of said rotatable members with said gates, and means forrevolving said members on their mountings.

2. In combination with towers, gates pivotally mounted near the base ofsaid towers, four-armed levers pivotally mounted near the topof saidtowers, links connecting two opposite arms of said levers with saidgates and the other arms of said levers with the corresponding arms ofthe levers on the opposite towers, pulleys at the top of one or more ofsaid towers, chains passing over said pulleys and connecting with theopposite arms of one of the before-mentioned four-armed levers and meansfor producing a tractional tension in said cords.

8. In combination with towers, gates pivotally mounted near the base ofsaid towers, rotatable members pivotally mounted near the top of saidtowers, links connecting two opposite extremities of said members withsaid gates and means for revolving said members on their pivotedmountings.

4. In combinat on with a pair of oppositely-disposed gates, rotatablemembers, connection between said gates and opposite extremities of saidrotatable members and means for actuating said rotatable members foroperating the gates equally and simultaneously.

5. In combination with towers, gates pivotally mounted near the base ofsaid towers, four-armed levers pivotally mounted near the top of sadtowers, links connecting two opposite arms of said levers with saidgates, cross connections between the other arms of said levers and meansfor revolving said fourarmed levers 6. In combination with towers, gatespivotally mounted near the base of said towers, levers pivotally mountednear the top of said towers, pulleys at the top of said towers, flexibleinstrumentalities passing over said pulleys and connecting with thehorizontal extremities of said levers, links connecting said extremitieswith said gates, and means for producing tractional tension in saidflexible instrumentalities.

7. In combination with towers, gates pivotally mounted near the base ofsaid towers, guides mounted near the top of one or more of said towers,rotatable members pivotally mounted below said guides, flexibleconnections passing over said guides and connecting with two oppositeextremities of said rotatable members and levers connecting the-othertwo extremities of said rotatable members with the correspondingextremities of the rotatable member of the opposite tower.

In testimony whereof I aHix my signature in presence of two witnesses.

WILLIAM WALTER MOORE.
